Induced Maturation of
Peneaus semisulcatus
A major success in the induced maturation of Penaeus semisulcatus has been achieved in the
breeding experiments conducted without resorting to eye-stalk ablation but through the
manipulation of certain environmental parameters at Mandapam
Regional Centre of CMFRI.
One of the methods employed to induce
maturation in penaeid prawns is through unilateral
eye-stalk ablation. A major success in the induced
maturation of Penaeus semisulcatus has been achieved
in the breeding experiments conducted without
resorting to eye-stalk ablation but through the
manipulation of certain environmental parameters at
Mandapam Regional Centre of CMFRI.
Acfiveand healthy specimens of P. semisulcatus
collected from the trawl catches were brought to the
hatchery. From these collections, males and females
(females after spawning) weighing 30-40 g were
sorted out and maintained in polyethylene pools of
2 m diameter provided with sand filter and
recirculation of sea water. Stocking density never
exceeded 3 animals/cu.m of water.
Two sets of experiments were carried out, the
first set with 4 males and 4 females and the second
one with 4 males and 5 females. In these experiments,
the pH of the sea water was maintained between
8.1 and 8.3. Salinity varied between 34ppt and
36ppt and temperature 23-28°C. The oxygen level
was between 3.8 and 4.5 ml/1. The light intensity of
the pool was kept at an average of 500 lux by
partially covering of the tank. The animals were fed
ad libitum with clams/squids/marine polychaetes.
In both the experiments 3 females positively
responded. Females moulted once in 1 5-20 days.
During this intermoult period, individual females
spwaned 2-3 times, the females after a moult took 3-

8 eight days (mean 5.8. days) for first spawning, 2-
6 days (mean 4.0 days) for second spawning and
3-5 days (mean 3.7 days) for third spawning.
Average production of eggs in the first, second and
third spawning were 1,42,000; 1,22,000 and

The campaign was inaugurated on 16 August
1993 by Hon'ble MIA Shri Dominic Presentation,
who reiterated the role of institutes like CMFRI in
human resource development. Dr. P.S.B.R. James,
Director, CMFRI, who presided over the session,
highlighted the relevance of technologies for culture
of clams and other molluscs for women in the locality.
Shri K.K.P. Panikkar, Sr. Scientist welcomed the
gathring, Dr. (Mrs.) Krishna Srinath, Sr. Scientist
explained the objectives of the campaign. Shri K.J.

vote of thanks. The valedictory session of the campaign
was held on 20 August 1993. Dr. K. Gopakumar,
Director, CIFT, delivered the valedictory address.

Division, CMFRI chaired the session.
An evaluation of the campaign indicated that
it was for the first time that needs of women in this
village were addressed integrating various aspects
of the problem. The participants felt that creating
awareness of financial support was crucial as people
were often misguided by local advices. Alcholoism
was the major problem which shattered their
household economy. The campaign recommended
for more such programmes concerned with the issues

confronting fishing community.
The campaign formed one of the activities of
the research project on "Empowering Rural Women
through Extension Education - An Action Research in
a Fishing Village". The extension programmes are
carried out through Matsyamahilavedi, a Society
framed by fisherwomen.
Training on Seaweed Recipes
preparation
A three months training for preparation of
seaweed red pes was organised for 30 fisherwomen
of Rameswaram area from 23 August 1993, in
collaboration with the Centre for Women Agriculture
and Rural Development under TRYSEM scheme. The
inaugural function was held on 20 August 1993 in
which about 50 fisherwomen, scientists from different
departments participated. The trainees were afforded
basic knowledge about seaweeds and their various
uses through a series of lectures. They were also
taught the identification of different commercially
importantseaweeds. Demonstrations were conducted
on the preparation of seaweed recipes such as
pickle, wafer and agar jelly. Dr. N. Kaliyaperumal,
Sr. Scientist and Officer in charge, Miss. Sheela
James, Scientist and Shri S. Kalimuthu, Technical
Officer of Mandapam Regional Centre of CMFRI
were involved in the programme.
Training on Pearl Oyster Culture
Pearl oyster hatchery training was given to
Miss. M. Theres, Laboratory Attendant, Pearl Culture
Project, M/s. TNFDC Ltd., Mandapam from 15July
to 5 August 1993 at Tuticorin Research Centre of
CMFRI.

Women to take the lead in
on-farm feed production
Motivating women for gainful employment in
prawn farming and related activities is one of the
important areas of extension work by the Institute. The
Institute has been organising educational programmes
in this aspect with the help of Matsyamahilavedi, a
society formed by women in fishing and fish farming
communities. Recognising the potential for women's
involvement the technology of on-farm production of
prawn feed was suggested to them and some
women were given training in it. The formulae using
the locally available ingredients such as prawn head
waste, tapioca and groundnut cake, and the ease of
production using simple machinery created enthusiasm
among the women. Due to comparatively low cost of
the feed, prawn farmers welcomed the initiative.
Training of women in prawn feed production
The first experimental project on household-
based prawn feed production by women was
bunched in South chellanam fishing village in Cochin
on 26 October 1993 by sanctioning a loan of
Dr. P.S.B.R. James, Director, CMFRI, inaugurating seminar
and training programme. Seated (Left to Right) Shri A.B.

Matsyamahilavedi. The loan was issued by the
Corporation Bank, South Cehllanam under the
refinancing scheme of NABARD at the ianaugural
session of the one-day seminar on prawn farming
followed by a 5-day training programme in prawn
culture for women.
The programme was inaugurated by Shri A.B.

With a view to extending the pearl culture
programme to the west cost of India, 800 mother
oysters and 200 spats were transported from Tuticorin
and transplanted at Cochin and Calicut during the
first week of October. The pearl culture is at present
confined only to the south-east coast of India.

Brood stock of clam, Paphia malabarica
brought from Ashtamudi lake and transplanted at
Tuticorin bay in August spawned in October and
November. Spawning in October was unusual and
only 25,000 larvae were healthy. In November
spawning, there were 10 million straight hinged
larvae which got reduced to 3.3 million 'umbo'
larvae. About 2.5 million spat could be obtained at
the end of November. Due to heavy rain in December
the Bay was flooded and the salinity dropped down
considerably resulting in the failure of mixed
phytoplankton production and reduction in the number
of the spat to less than one million.
A whale shark, Rhiniodon typus was caught
by a purse seiner near Ganguli at a depth of 24 m
on 6 December 1993. The shark which is locally
known as dodda koppalaka was 3.2 m in length
and 500 kg in weight. Reported by Shri. Ganesh
Bhatkal, Bhatkal Field Centre.

tonnes of Decapterus russelli. The fishing was done
during night at a depth of 20-30 m.as reported by
